How To Build A Fuel System
To route both the motor and nitrous AN-8 lines clear of the suspension and other obstructions, we used Adel clamps (arrow A) supplied with the BG 220HR kit and a few extra ones that we bought at a local hardware store. We used many existing holes and drilled a few new ones. We also fashioned tie-downs from zip ties (arrow B) that hold the braided lines together yet keep them from rubbing against each other, which will eventually fray the braided covers. Fuel flows directly into the carburetor bowl inlet via a braided fuel rail. After flowing through the rail, the fuel hits the bypass regulator and excess pressure is bled back to the tank through the return line. This keeps the fuel pressure in the system at the preset level, which we set at 71/2 psi. On the nitrous side, fuel will be pumped directly from the tank to the nitrous system’s fuel enrichment solenoid, with the excess returned to the tank. This setup minimizes the risk of a drop in fuel pressure when the system is activated. View Related Article
